Correct answer: A — Offer pertussis-containing vaccine now because it is recommended in every pregnancy
Pertussis vaccination is recommended during every pregnancy so maternal antibodies transfer to each baby. At 20 weeks she is within the recommended window, with vaccination ideally given before 32 weeks for maximum protection, although later vaccination may still benefit the mother and infant. The vaccine is not live. A dose in a previous pregnancy does not provide optimal passive protection for this baby, and routine infant vaccination begins later rather than replacing antenatal protection.
